Congrats on your new ride! She's a beauty
Sucks that you had such a crappy dealership experience. I've been working direct with the Sales Manager at BMW Seattle for my last ~8 new cars, and have always had an amazing experience. He even hooked me up with an i3 to play with for a couple of days while my X650i was in for the "not recall recall", knowing full well I wasn't going to buy one.
Some dealers never seem to learn how much loyalty matters - honestly one of the (many) reasons I'd not leave BMW is the service (both pre and post sale) I've had. You'll now be an Audi customer unless they do something to lose you!
